I've got to buy more caps, as there is slight distortion in the bass sound. Probably one of the discolored coupling caps near the 6V6GT tube.
Its reasonably sensitive on AM and SW. Police band is quiet, but I have heard things here, too.
I snatched the bakelite knobs off of an RCA radio for now. It really looks nice, too. I still need to get the original styles if possible.
Now, onto the RCA which needs caps, and a big Philco with lots of Loktal tubes that needs caps, too.

Nice score!
Preemptive recapping is indicated on all old radios in original condition; those wax-paper bad boys are usually up to mischief after the set warms up.
The so-called "police band" is usually quiet these days. There is a weather service that broadcasts sometimes just a few KC above the AM broadcast band IIRC, but it's a slop-bucket transmission, meaning you would need to improvise some kind of BFO to copy.
Where did you obtain those 20-550 'lytics?
